Abstract: A pneumatic insert for a pneumatic tire comprises a generally toroidal-shaped hollow tubular member with beads, that includes an insert inflation chamber pneumatically noncommunicable with the tire inflation chamber. A crown portion of the insert has a radially inner and a radially outer layer that define a closed lubricant chamber, also noncommunicable with the tire inflation chamber under normal running conditions. Lubricant release means such as valve or diaphragm provided in the outer crown layer permit release of the lubricant when the tread collapses against the insert crown during run-flat conditions.
